there's been a countless number of players who got hype solely based on their athleticism. the difference between the players like green and players who become solid players in the nba is their will to improve and the effort they put in to become a better player

"potential" may get you into the league, but hard work is the only recipe to stay in. that's also what separates good players from great players. look at kobe and lebron- they weren't even close to the players they are right now when they entered the league. it's all about hard work. great players improve every single year
